For the shaft application designed in Problem $1$ perform a preliminary specification to choose $02-$series deep$-$groove ball bearings from Table $11-2$ to support the shaft at $O$ and $B.$ The shaft rotates at $1000rpm.$ Consider the case where the shaft is operated during one work shift $(8$ hours per day, $5$ days per week, $50$ weeks per year$)$ for $2$ years, with a reliability goal for the bearing pair of $98\%$ and very clean lubricant is maintained throughout the bearing life. Use an application factor of $1\mathrm{.}2$ and assume the distribution data from manufacturer $2.$

$****$ Tables$/$Charts can be found in Class Activities or Class Lectures $****$

Determine the followings:

From problem $1,$ use the FBD of the forces acting on the shaft to find the resulting reactions at support locations $O$ and $B.$

If identical bearings are to be used at both locations $),$ which bearing location is critical and what is the radial load $F_D$ at this location?

What is the desired life $L_D$ and bearing reliability $R_D?$

Find the catalog load rating $C_{10}$ of the maximum radial load.

Choose $02-$series deep$-$groove ball bearings from Table $11-2.$
